Title: Improvements in or relating to warp knitting looms or machines and fabrics produced thereon
IPC: D04B23/08
Filed: 1962-11-15
Abstract: A warp knitted fabric comprises two separately knitted ground fabrics with a fibrous staple web therebetween the staples of which web are interknitted or interlocked with both ground fabrics.  The duplex fabric thus produced may be slit or divided by cutting through the staples of the fibrous staple web so as to provide separate lengths of the ground fabric each with a warp pile surface.  The fibrous staple material is fed in a continuous film and is drawn in by the knitting action alone.  The fibres may be of vegetable, animal, cellulosic nylon or other man-made origin.

Title: Control circuit for hydraulic machine
IPC: F15B13/01
Filed: 1975-10-23
Abstract: 1493288 Valves CATERPILLAR TRACTOR CO 23 Oct 1975 [5 March 1975] 43642/75 Heading F2V [Also in Division G3] Overrunning of a ram 16 when lowering a heavy load is prevented by a valve 122 which throttles the release of fluid from space 116 above a valve 58 in the exhaust line 42, 60 from the ram, the valve 122 being actuated in accordance with the pressure in the exhaust line and co-operating with a further throttle valve 102 through which pressure is applied to the space 116. A pump 46 supplies the ram 16 through a valve assembly 10 containing fluid-pressure operated inlet valves 52, 54 and return valves 56, 58 controlled by spools 64, 102 which may be progressively adjusted by pressure from a pilot pump 20 in response to manual operation of a spool 30. To lift the ram 16, the spool 64 is displaced by pilot pressure in a conduit 38 against springs 66 and 83 so that fluid from the main inlet 44, 50 flows through passages 84, 76 to a space 78 to open the valve 54. At the same time, a space 68 above the valve 56 is connected through metering slots 94 with an exhaust line 80 to regulate the lift of the valve 56. If pressure in the return line 40 from the ram becomes excessive, a pilot valve 98 is opened to by-pass the metering slots. To lower the ram, pilot pressure is applied to a conduit 36 to displace the spool 102 and open the inlet valve 52, the space 116 above the return valve being connected to exhaust through the valves 102 and 122. The ram retracts at a velocity slightly greater than that which can be created by pump flow, and a pair of make-up valves 132, 134 permit fluid to be drawn from a drain passage 60 into the respective motor conduits 40, 42. When the pilot pump 20 is stopped, a spring 144 shifts a valve 136 to the right to permit fluid from the ram to flow by way of a shuttle valve 26 to the manual spool 30. The spool 102 may thus be operated to lower the ram. In a second embodiment, the inlet valves are operated by pressure from the main inlet (50<SP>1</SP>), Fig. 3 (not shown), controlled by further valves (164 and 178) responsive to pilot pressure in lines (36<SP>1</SP> and 38<SP>1</SP>) communicating with a manual spool similar to that disclosed in Fig. 19 of Specification 1,302,741. In a third embodiment, only one inlet valve (220) Fig. 4 (not shown) is employed and metering slots (238) on a pilot-operated spool (240) provide control of the return flow from a single-acting ram (228).

In one embodiment, each of two switch units 1, 2 is provided with two interlocked switch bodies 10 each housing a spring biased contact 16 which bridges a pair of fixed contacts 19, 20. Positioned within each pair of interlocked bodies 10 is a control barrel 11 housing bores 15 which accommodate balls 14 or pins (38a) Fig. 5 (not shown) in the closed position of the switch. When the control barrel 11 is rotated by rotating a spindle 22 by a handle 24 or a key, the balls 14 (or pins 38a) are forced out of the bores 15 to move the bridging contacts 16 away from the fixed contacts 19, 20. Mounted on the spindle 22 which is held in position by a spring clip 33, is an indexing device 3 comprising a cam wheel 30 which co-operates with spring biased balls 26 to provide indexed switch positions. The cam wheel 30 is also provided with an annular channel 34 accommodating a fixed projection 6a on an end plate 6 which engages, when the spindle 22 is rotated, stop blocks (35, 36) (Fig. 2, not shown) selectively positioned in the channel 34 so as to limit the movement of the spindle 22.

A circuit for gating one only of a number of inputs to an output comprises a number of transistor bi-stable circuits each operating as a gate and having an emitter impedance common with transistors of the other circuits so that when one circuit is set to open a gate the others are reset. The right hand transistors of the bistable circuits shown normally short-circuits to earth the path between terminals such as 30, 31. Momentary operation of one of the switches changes the state of the circuit, opening the corresponding gate. Momentary operation of a further switch likewise opens its corresponding gate, the voltage developed across the common emitter inductor, or a common resistor restores the previously operated gate. Fig. 3 (not shown) is a similar circuit arranged to connect one of the input terminals (such as 30) to a common output-terminal (31), the switches being arranged so that if two are operated the one on the left has priority. The switches may be electronic organ pedals for gating desired oscillators.
